The penalty phase of the case is underway that will determine if Antolin Garcia-Torres gets the death penalty or life without parole.

They knew as they arrived at the courthouse that this would be an emotional day. It was time for Marlene and Steve LaMar to give victim impact statements, to let the jury know how their daughter's death has affected them.

Marlene sobbed on the stand, finding it difficult to contain her sorrow as she talked about Sierra as a caring person who loved to dance. The hardest part was watching a video of Sierra smiling and lip-syncing to a song.

"It's the first time that I heard her speak live on a video, so that was really hard because I've been avoiding that because it's been so painful just to look at videos of her. But I've been doing it a lot lately this past month," mother Marlene said.

Father Steve also fought back tears watching the video, describing Sierra as goofy and playful with an infectious laugh."Hard, it's still hard," he said. "For a long time, probably have only been able to watch videos of Sierra in the last year or so, and it's still hard. I still cry."

Tears filled the eyes of several jurors, while convicted killer Garcia-Torres avoided eye contact and didn't look at the slides and video.

The jury looked sad. "The part of the case now is about impact on this jury and what is their moral decision, so there's no question the fact they were emotionally affected by this testimony, will likely have an impact on their decision," legal analyst Steven Clark said.
